Transfer only files that do not exist - wildcard based.

Transfer only files that do not exist - wildcard based.

First off, I am pretty sure I cannot use the Synch command.
Remote Folder contains thousands of files.
Local Folder contains only a handful of files until they are processed, then they are moved to an archive folder.

I need to be able to transfer just today's files from remote to local, but I do NOT want to overwrite.

All the script examples I see have the following 2 lines:
option batch on
option confirm off

This will overwrite the files which I do not want.

I tried writing a script that said:
get 20091101*
w

In the hopes that the ne(w)ew option would be send to the prompt that appears when a file already exists, but no joy

So is there a way to only transfer newer files based on a wildcard as opposed to Synch mode?

I would love to see something simple like: option confirm newer
That would answer w for me for all file copy collisions.
